Oil tops $100; shipping chokepoints stack up
Oil prices climbed back above $100 after U.S. moves to blockade Iranian ports and the failure of talks, and reports say tankers are being stranded in the Gulf amid heightened naval interdiction. At the same time, draft restrictions and climate stress at the Panama Canal and other routes are forcing reroutes and capacity limits, widening transport and energy risk. ((bbc.com)) ((archyde.com))
Oil jumped back above $100 a barrel on Monday after the United States said it would begin blockading ships entering and leaving Iranian ports. (cnbc.com) Reuters reported the blockade order followed weekend talks in Islamabad that ran from Saturday into early Sunday and ended without a deal. United States crude futures rose more than 8% to about $104.80 a barrel in early trading. (usnews.com) (cnbc.com) The Associated Press said the United States military was preparing to block ships entering or leaving the Strait of Hormuz, where shipping had already been heavily disrupted by the war. CBS reported President Donald Trump said the blockade would begin at 10 a.m. Eastern on Monday and that vessels avoiding Iranian ports would still be allowed through part of the strait. (apnews.com) (cbsnews.com) That waterway matters because the Strait of Hormuz carries about 20 million barrels a day of crude oil and petroleum products, or roughly one-fifth of global consumption, according to the International Energy Agency and the United States Energy Information Administration. The Energy Information Administration also said around one-fifth of global liquefied natural gas trade moved through Hormuz in 2024. (iea.org) (eia.gov) The pressure is not limited to the Gulf. The Bab el-Mandeb Strait at the southern end of the Red Sea handled 12% of seaborne oil trade and 8% of liquefied natural gas trade in the first half of 2023, and the Energy Information Administration said oil flows there fell by more than 50% in the first eight months of 2024 as ships diverted away from the route. (energy.gov) (eia.gov) The Panama Canal is a different kind of chokepoint: it runs on freshwater from Gatun Lake, so low rainfall can force limits on how deep ships can sit in the water and how many vessels can cross each day. The Panama Canal Authority’s current 2026 advisories show booking and lane-management changes are still active even after traffic recovered from the 2023 and 2024 drought. (pancanal.com 1) (pancanal.com 2) A Nature study published in 2025 estimated that disruptions at major maritime chokepoints cause about $10.7 billion a year in economic losses, plus another $3.4 billion in freight costs. The paper found the biggest losses come from the Suez Canal and Bab el-Mandeb because detours can add 5,000 to 12,000 kilometers to a voyage. (nature.com) Iran has threatened retaliation, according to Reuters, and the market reaction shows traders are pricing not just lost barrels but lost flexibility. When several narrow routes are under pressure at once, shippers have fewer places to reroute cargo, and each delay pushes up fuel, insurance and freight costs. (yahoo.com) (nature.com)
